LESTER S. GUNDERMAN, OF PITTSBURGH, PENNSYLVANIA.

SAFETY DEVICE FOR CLOTHES WRINGERS.

Application led March 7, 1923. Serial No. 623,379.

To all whom t mayycoaeem:

Be it known that I, LESTER S. -GUNDER- MAN, a citizen of the United States, residing at Pittsburgh, county of Allegheny,

State of Pennsylvania., have invented certain new and useful Improvements in Safety Devices for Clothes Wringers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on drawings representing like parts. l

This invention relates to a certain new and useful improvement in a safety feeding device which enables the operator to feed the clothing to the press-rolls without using the hands as is the ordinary custom.

In this practice with power driven rolls the fingers often-times. become caught between the press-rolls and are badly injured.

The object of this invention being to provide a feeding device which can be readily attached to the ordinary wringe now in use, whereby the clothing will be fed to the press-rolls.

It is an object of this invention to construct a feeding device having an improved automatic adjustable feeding-bar to take care of the different thicknesses of clothing 30 being fed to press-rolls. A

A further object of this invention is to provide means for holding clothes away from the lower edge of wringer and obviate the use of the hands in drawing the clothing out from under press-rolls while being run through the said press-rolls. This device forms a guard over the feeding mechanism when it is out of use or in an ineffective position.

It is a further object of this invention to construct a feeding device that has novel means of automatic adjustment of feed bar for different thicknesses of clothing being fed to press-rolls.. p My invention herein described embodies new improvements over those shown in my application for Letters Patent filed Nov. 16, 1922 and Serial No. 601253 now Patent No. 1,505,334, dated Aug. 14, 1924,and has 50 certain advantages over structure there illustrated.

Other and further objects and advantages of this invention will be herein set forth and the novel features thereof defined by the appending claims, so much only of the wringer frame and accompanying parts are illustrated'as deemed necessary to describe the parts which are applied thereto.

Fig. 1 is a front elevation of a wringer frame and rolls, to which my improvements are applied. v

Fig. 2 is a section View taken on line X-i Fig. 1, and shows the position that my improved feeder takes 4when in an ineffective position or at rest.'

Fig. 3 is a section View taken on line Y--Y Fig. 2.

n Fig. 4 is an enlarged section taken on line X-X and shows position feeding bar tallles in feedingthick clothing to the press ro s.

Fig. 5 -is an enlarged section taken on line X-X and shows position feeder takes in feeding thin clothing to press rolls. The dotted line shows more clearly the rise and fall of feed bar.

In a more particular description of the parts, 7 designates the upright frame member of the wringer. 8 designates upper transverse members which unite the uprights. 9 and 10V designate the usual wringer rolls which are drivenfrom one end ina well known manner. 11 designates guards at end of press-rolls which is of a well known form.

Thus far the elements referred to embody well known conventional parts of power driven wringer.

My improved construction of feeding device comprises a pair of brackets 12, upon which are mounted formed link members 13 by bearings 14, feed bar 15 is mounted to formed link member by bearings 16; one.

end of link members 17 is connected by bearings 18 to feed bar 15. The opposite end of link members 17 is provided with a slot 19 and connected to member 12 by stud shaft 20. Feed bar 15 is provided with handles 21 to swing the feeding mechanism upward to feed clothing between press-rolls.

It is desirous to have the feed member move to ineffective position, for this purpose bar be stopped just as the press rolls have grip d the clothing. The upper edge ofhan les will abut on upper edge of opening 24, when springs return feed mechanism to ineffective position, handles .will abut on lower edge of opening 24.

Space 25 is where clothin is placed by the operator when readytoy forced upward and inwardv between press-rollsyby feed bar 15. Said feed bar has flanges on each end to provide' space for stud bearings and its outward surface is preferably of a curved shape, handles 21 being secured at each end to said feed bar. formed link member 13 extends from one bracket to the other bracket. It is to be understood that formed link member 13 can be made from several pieces and then connected together by a separate plate.

Cover 23 is formed in a semi-circle to give as little resistance as possible to clothing when they are being drawn over the cover by press-rolls. It is to be understood that this form of my invention herein shown and described is to be taken as a preferred design of the same, and that various minor changes in the'shape and arrangement of the parts may be resorted to Without -de parting from the spirit of the invention or scope of the claims.

Claims.

1. An attachment for a clothes wringer frame having 'presser rolls, comprising a pair of brackets mounted on the wringer frame, a link member with the lower end pivoted to each of said brackets, a feed bar with the lower end hinged to the outward extended end of the linki members, said members guiding the movement of said feed bar, link members having slotted bearings, having one end of each slidably connected to each of said brackets and the opposite ends mounted to side flanges on said feed bar for guiding the upper edge of said feed bar, when feeding dierent thicknesses of clothes to the presser rolls, a pair of handles secured to said 'feed bar to move said feed bar to the bite of the presser rolls, and a cover plate mounted on said brackets for protecting said feed bar when in an inoperative position.

2. An attachment for a clothes wringer frame having presser rolls, comprising a pair of brackets mounted on the wringer frame, a link member, with the lower end pivoted to each of said brackets, a feed bar with the lower end hinged to the outward extended end of the 11nk members, said ymembers guiding the movement of said feed extending upward and pivotallyl bar, link members having slotted bearings, having one end of each slidably connected to each of said brackets and the opposite ends extending upward and pivotally mounted to said feed bar for guiding the upper edge of said feed bar, in feeding clothes to the presser rolls, springs, one end of each being connected to the feed bar and their other ends being connected to the said brackets to automatically move the feed bar to inoperative position, a cover plate mounted on said brackets for protecting said feed bar when in said inoperative position, a pair of handles secured to said feed bar and extending outward through openingsv in the said cover plate for operating said feed bar, said handles abutting the upper edges of said openings when the feed bar is raised upward and fairly contacts with the presser rolls andsaid handles abutting the lower edge of said openings when the feed bar is in an inoperative position, thereby giving the said feed-bar a prescribed limited movement.

3. An attachment for a clothes wringer frame having presser rolls comprising a pair of brackets mounted on the wringer frame, a link member with the lower end pivoted to each of said brackets, a feed bar with the lower end hinged to the outward extended end of the link members, said members guiding the movement of said feed bar, link members having bearings with one end of each connected to each of said brackets and the opposite ends extending upward and mounted to said feed bar for guiding the upper ends of said feed bar, when feeding clothes to the resser rolls, a cover plate mounted on sa1d brackets for protecting said feed bar when in an inoperative position, said plate being shaped to leave a space between the upper parallel edge of said guard and the presser roll for placing clothes on the edge of the plate to be carried to the bite .of the presser rolls, a pair of handles secured to the feed bar for operating said feed bar, said handles extending through openings in said plate and which when moved upward abut the top edge of said opening and which, when moved downward, abut the lower edge of said openings, hereby controlling the throw of said feed In testimony whereof, I have hereunto Set my hand.
